superagent global 401 handler

I am using superagent to do my ajax data fetching job.

request
    .get('/some/end/point')
    .end(function(err, res) {

        if (err && res.status === 401) {
            // redirect to login
        }

        // do something with res.body

    });

many of my request need authentication check, but is that possible to config if (err && res.status === 401) {} globally?

or I should repeat the code in every request I make ?

You can use like this:

var unauthorizedRedirect = function(req) {
  req.on('response', function (res) {
    if (res.status === 401) {
      console.dir('redirects')
      // redirect to login
    }
  });
};

request
  .get('/some/end/point')
  .use(unauthorizedRedirect)
  .end(function(err, res) {
    // do something with res.body
  });

@allces

function authorizedGet(url) {
    return request.get(url)
        .use(unauthorizedRedirect);
}
